(c1. 10i-99) This invention has for its objectl a music printing machine.

Printing music by handis a long and complicated operation necessitating the cooperation of experienced and very skillful operators. `In. fact, 5 this work presents diniculties partly ycaused by the fact that musical signs are of great variety in form and are not aligned as the letters of a text on one and the same horizontal line, but are distributed on the lines constituting the stave or extend beyond this` stave sometimes above the latter and sometimes below the same. Another difilculty of this work arises from the fact that the distance between two musical signs is not always the same and depends on the value of lthe note and on the number of signs it is necessary to insert in a bar of the musical text.

The music printing machine forming the sub-A ject-matter of the invention, by which the printing of music is made very easy and allows this work to be rapidly executed by unskilled operators, is mainly characterized by the fact that it comprises a table on which can move a frame carrying the paper on which the `printing of music is to be eiected, a carriage movable relatively to the table and carrying punches on which the different music characters are secured, which carriage can be moved by the operator so as to bring the punch carrying the character toy be printed in front of a jointed lever actuated by a driving mechanism; a source of light provided with a suitable optical system producing a light ray is arranged on the table so that the light ray produced strikes the paper, by passing through an opening provided in the tableand having Va glass plate, and materializes the point Where the punch, acted upon bythe lever, strikes the paper, this allowing adiustment'of the frame in the required position and the printing of the sign at the suitable place.

The invention is further characterized by the following arrangements:

(l) the jointed lever, acting on the punches carrying the type, is subjected to the action of a cam which imparts two downward movements to the said lever; during oneV of these movements, the type carried by the punch on which the lever acts, comes in contact with a small movable inked table, subjected to the action of a"lever, the movements of Ywhich take place in synchronism with those of the jointed lever acting on the punches carrying .the type; during the other of the said; movements, the type carried -by the punch comes in contact with the `paper Yand prints it, the inked table being Amoved away during this time;

(2)` a pedal actuated by the Voperator allows a clutch to connect a suitable motor to the mechanism driving 'the punches and the inking device for printing each type, eachv depression of the pedal producing the printing of a type;

(3) the carriage carrying the type is provided with a rack meshing with a toothed wheel which can be actuated by the operator vby, means of a. handle,l in order toi move the punch carrying the suitable type in the plane in which the jointed lever moves. In order that the invention may be clearly understood, an embodiment of the same is described f 1-0 hereinafter, by way of example only, with reference to the accompanyingdrawings, in which:

Fig. l is an elevation, partly in section, of a music punching machine.l

Fig. 2 is a plan view. y

Fig. 3 is a partial elevation, partly in section, on an enlarged scale.

Fig. 4. is a partial plan view, partly in section, on the same scale as Fig. 3.

The music printing machine illustrated in the; accompanying drawings, comprises: a table I, carried by a frame 2 on vwhich are securedV a Y motor 3 producing the motive power', a box-like frame 4 enclosing the driving mechanism for the punches 5 and the inking table 6, and supporting the carriage 'I carrying the punches, amechanism for driving the carriage 1, and -a frame' 8 carrying the paper with its guide device.

They frame 2 has an inclined face on which the table I is secured. Under the table I is at- 30 tached a bracket 9 carrying a lamp I@ and an optical system II concentrating Vthe light raysemitted by the lamp in a bundle of very small diameter; an opening I2 formed in the table allows the passage of this bundle, and a glass plate I3 supports the'paper id at this opening' I2.

The carriage 'I, which moves on rollers I5 carried by the box-like frame 4, carries the punches Y 5 at the lower end of which the type lare respectively secured. YVEach punch 5 is constantly 40 subjected to the action of a spring I I tending to lift it. On the carriage 'I is secured a-rack I8 meshingL with a toothed wheel I9 keyed'. on one end of a shaft v2li carying, at its other end, another toothed wheel 2l meshing with a pinion 22 driven by a crank 23. The toothed wheels le, 2i, the toothed pinion 22 and the rack I8 are so chosen that for one half revolution lof the crank 23 the carriage "I progresses in one direcy tion or the other according to a distance equal to that separating the axes of pairs of punches.

The motor 3V drives a speed reducing device 14 which'transrnits the movement to a shaft 25. A clutch 2@ (of the type used in cutting out or flanging presses), which is actuated bya lever ,55

2l to one end of which is pivotally connected a link 2S rigid with apedal '29; allows the shaft 25 to be rendered rigid with a shaft 30. A'spring v3i acts on the pedal 29 and constantly tends to raise it; in the raised position, the shafts 25160 tion.

and 30 are no longer rigid and do not rotate together. The shaft 30 extends within the box-like frame 4 and carries a toothed wheel 32 and a cam 33. The toothed wheel 32 meshes with another 1toothed wheel 34 4mounted on a shaft 35, which carries another toothed wheel 35 and a cam 31. Finally, the toothed wheel 3B meshes with a toothed wheel 38 mounted on a shaft 39 carrying two cams 453 and 4i and an inking cylinder 42. The cam 31 acts on va rollerr43 carried by a pivoted lever 44 which is keyed o na shaft 45 rotating in bearings 45.

On the shaft 45 is keyed a lever 41 on' the free end of which is pivotally mounted a pawl 48 in engagement with a pawl wheel 49 driving a shaft 5B on whichacylinder 5I is mounted. This cylinder 5I is arranged in a cup 52; a small plate 153-arra'nged on the bottom of this cap 52, which serves as a receptacle for printing ink, leaves on the surface of the cylinder 5l only a thin ilm of ink. f

A cylinder 54, pivoting about a shaft 55 supported by two levers 55 keyed on a shaft 51, alternately comes in contact with the cylinder 5I -and'with the inking cylinder 42, and transfers 'the ink which itV collectsfrom the cylinder 5I,

to the cylinder 42; this reciprocating movement -fbeing produced by a'lever '58 keyed on the shaft `its freeend, a roller 66 moving on the cam 4I A' -Y-shaped vlever 61, pivoted, at the free ends of `itsrtwo branches, on the shaft 45,' carries a roller S8 Ywhich is in contact withthe cam 33, and

the free end oflthe lever 51 acts on the punches 5; a spring 69 secured at one of its ends to the lever 51, and at its other end, to the box-like frame 4, constantly maintains the roller 68 on Aspring'l, also' secured at oneof its ends to the box-like frame 4 and at its other end to the lever 44, constantly'holds the roller, carried by vthe said lever 44, against the cam 31.

The frame 8, on whioh'the paper I4 is secured,

.ispivotally mounted on one of the ends of two I rod-like links 1i, of equal length, which are each -pivoted, at theirother end, on a gusset 12, this gusset beingpivotally connected to one of the Yends yor two Aother links 1.3, of the same length, the other end of which is also pivotally connected tothe table I. This linkage enables the frame 8 andpaper I4 to be moved in any direction but always in parallelism with itself.

'The paper I4 being secured on the frame 8, the

4light bundle, emittedbi7 .the lamp I5 and the Vthe latter is translucent; this spot` of light indicates the point of impact on the paper of the `type 16 carried by the punch-5 under considera- Consequently, the operator, by Vmoving the frame A8, can determine the printingtof a type at the desired place.

The carriage 1 is moved by: acting on the crank 23, and the punch carrying the required type to be printed is brought opposite the lever 51.

For each printing of type, the operator must act onthe pedal 29. Upon each'depression of the .pedal 29, the link 28 causes the lever 21 to pivot,

this lever acting on the clutch 26, and the latter lrenders the shaft 3B rigid with the shaft 25 driven by the motor 3 during a revolution of the shaft 25, then the clutch 26.ceases to act.

Theclutch 26 will cause the shaft 3G to again Vbe 'rigid with the shaft 25 only when the operator depresses the pedal again.

For each revolution of the shaft 30, the cam 33 imparts two movements to the lever1 61, the roller 63 of which rolls on thesaid cam; during one of these movements,l the lever 61, urged by the spring 39, pivots about the shaft 45 and presses, by its free end, on'the punch 5 located in its plane of oscillation, the punch 5 moves down and the type I5 it carries comes in contact with the inking table 5 which hasV come under the punch 5 owing to the action vof the lever E5 keyed on the shaft 45; then, the punch 5 moves up again, the

' cam 33 acting on the lever G1 in opposition to the action of the spring B9, the inking table 5 moves away under the action of the lever 50, and, iinally, the punch 5 moves down again, the lever 61 being again subjected to the action of the'spring 69. The type I6 carried by the punch then effects an impression on the paper I4.

The rotation of the shaft 3B determines, owing to the gears 32, 34, Y36 and 38, the rotation of the inking cylinder 42 and the rotation of the cams 40 and 4I. The cams 4B and 4I producing the rocking movements of the levers 58 and 65 controlling the cylinders 54 and 6I, the cylinder 54 comes in contact with the cylinder 5I receiving the ink contained in the cup 52, is covered with ink, and then comes in contact with the cylinder 42 which is thereby covered with ink.

l The lever 41 carrying the pawl 48 also receives rocking movements and the pawl 48 imparts to the cylinder 5I a rotary movement during which the latterV is covered Vwith ink.
